Hadith 3:39
Umm Salama said, “I offered the Prophet a roasted flank and he ate some of it, then rose to pray without performing ablution.” Ahmad transmitted it.
وَعَن أم سَلمَة أَنَّهَا قَالَتْ: قَرَّبْتُ إِلَى النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ جَنْبًا مَشْوِيًّا فَأَكَلَ مِنْهُ ثُمَّ قَامَ إِلَى الصَّلَاةِ وَلَمْ يَتَوَضَّأْ. رَوَاهُ أَحْمَدُ
